Description

CROSS-REFERENCE TO RELATED APPLICATIONS Error! No sequence specified. This application claims the benefit of Japanese Patent Application No. 2023-54580, filed on Mar. 30, 2023, and Japanese Patent Application No. 2023-119829, filed on Jul. 24, 2023, of which the entirety of the disclosures is incorporated by reference herein. FIELD OF THE INVENTION This application relates to a trestle. BACKGROUND OF THE INVENTION In an attachment structure of a panel described in Unexamined Japanese Patent Application Publication No. 2006-57357, a crosspiece member is fixed to a support piece disposed on a support tile via a fixture. In the crosspiece member, a groove portion that extends in the longitudinal direction is formed, and a panel is attached via an attachment mounted in the groove portion. However, in the attachment structure of a panel described in Unexamined Japanese Patent Application Publication No. 2006-57357, there is a problem in that the attachment is not stable on the crosspiece member when the panel is attached to the crosspiece member and efficiency of attachment work of a panel deteriorates. The present disclosure has been made in consideration of the above-described circumstances, and an objective of the present disclosure is to provide a trestle capable of improving efficiency of attachment work of a panel. SUMMARY OF THE INVENTION In order to achieve the above-described objective, a trestle of the present disclosure is a trestle for installing a panel at an installation place. The trestle includes a base portion fixed to the installation place, a crosspiece portion supported by the base portion, and an attachment portion for attaching the panel to the crosspiece portion. The attachment portion includes a first attachment portion to press the panel in a pressing direction pointing toward the crosspiece portion and clamp the panel between the first attachment portion and the crosspiece portion and a second attachment portion placed on a placement surface of the crosspiece portion, and the first attachment portion is combined with the second attachment portion in such a manner as to be able to slide the panel in the pressing direction. On one attachment portion of the first attachment portion and the second attachment portion, an insertion portion that extends in the pressing direction may be formed, and on the other attachment portion, an inserted portion into which the insertion portion is inserted and that enables the insertion portion to move in the pressing direction may be formed. The insertion portion may be a projecting plate portion that projects from the first attachment portion in the pressing direction, and the inserted portion may be an insertion groove into which the projecting plate portion is inserted and that is formed on the second attachment portion. The first attachment portion may include two side wall portions arranged facing each other, a joining plate portion connecting one edge side of the two side wall portions to each other, and extended portions each extending outward from one of the other edge sides opposed to the one edge sides of the two side wall portions, and the projecting plate portion may project from the joining plate portion in the pressing direction. A groove portion that extends in a direction in which the crosspiece portion extends may be formed from an outer circumferential surface of the crosspiece portion toward an inside, the attachment portion may include a bolt inserted into the first attachment portion and the second attachment portion and a nut screwing onto the bolt and housed in and locked to the groove portion of the crosspiece portion, and the panel maybe clamped between the extended portion and the crosspiece portion by an axial force introduced into the bolt. The nut may be formed in a quadrilateral shape having a longitudinal direction and changes an attitude between a first attitude in which the longitudinal direction is aligned with an extending direction of the groove portion and the nut is freely removable and insertable from and into the groove portion and a second attitude in which the nut has rotated about an axis of the bolt from the first attitude and the nut is caught by the groove portion. On portions by which the nut and the groove portion come into contact with each other, a protruding portion and a recessed portion that engage with each other may be formed. The second attachment portion may include a locking portion coming into contact with a surface of the panel on an opposite side to a surface of the panel on which the first attachment portion presses the panel. The second attachment portion may include a bottom wall portion coming into contact with a placement surface of the crosspiece portion, a first rising portion rising from the bottom wall portion, a second rising portion rising from the bottom wall portion with a gap interposed between the first rising portion and the second rising portion, and the locking portion extended
