Abstract
Description
Technical Field
[0001] This utility model relates to the field of reinforced concrete roof truss technology, specifically a prefabrication mold for the web members of a flat warehouse folded-line roof truss. Background Technology
[0002] Flat-roofed warehouses typically use precast molds for the web members of a zigzag roof truss. However, the traditional construction process for zigzag roof trusses uses wooden molds for the bottom and side molds. This process has several drawbacks, including difficulty in handling the wooden molds at joints, the tendency for the molds to bulge and crack during concrete pouring, numerous construction joints after pouring, poor quality of precast components, long installation cycles for the bottom and side molds, cumbersome installation of the web members, low production efficiency, and the need for a large amount of manpower during on-site construction. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a prefabricated mold for the web members of a flat warehouse folded roof truss, which can effectively solve the problems in the background art.
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a prefabricated mold for the web members of a flat warehouse folded roof truss, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model discloses a prefabricated mold for the web members of a zigzag roof truss in a flat warehouse, including a mold base. A trapezoidal steel template is located at the corner of the mold base and is fixed to the ground. A wooden template is located on the mold base between two trapezoidal steel templates. An adjustment mechanism is located on the trapezoidal steel template, including a fixed plate and a sliding plate on the right side of the fixed plate. A retractable bolt is located between the fixed plate and the sliding plate, with one end connected to the fixed plate and the other end connected to the sliding plate. A clamping block is located above the wooden template and is fixed to the ground.
[0006] The trapezoidal steel formwork includes a base plate, with vertical side plates at the edges of the base plate, and a first fixing bolt at the bottom of the base plate, which fixes the base plate to the ground.
[0007] The fixing plate is fixed to the vertical side plate.
[0008] The retractable bolt includes a bidirectional screw and a threaded sleeve. The threaded sleeve is fixed on the fixed plate and the sliding plate respectively, and the bidirectional screw is threadedly connected between the two threaded sleeves.
[0009] The wooden template is convex in shape, with contact plates on both sides, which contact the sliding plate.
[0010] The clamping block includes a square timber, which is located above the wooden template. The square timber has second fixing bolts on both sides, and the second fixing bolts are fixed to the ground.
[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the trapezoidal steel template at the node, this utility model prevents the problems of easy formwork expansion and cracking during concrete pouring and poor forming quality of precast components. By setting the adjustment mechanism on the trapezoidal steel template, it prevents the problem of the wooden template being too long or too short to install, and makes the wooden template firmly stuck between adjacent trapezoidal steel templates, avoiding problems such as formwork running away.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0018] like Figures 1 to 4As shown, this utility model discloses a prefabricated mold for the web members of a zigzag roof truss in a flat warehouse. The technical solution adopted includes a mold 1, a trapezoidal steel template 2 at the corner of the mold 1, a base plate 201, a vertical side plate 202 at the edge of the base plate 201, a first fixing bolt 203 at the bottom of the base plate 201 to fix the base plate 201 to the ground, a wooden template 3 on the mold 1 between the two trapezoidal steel templates 2, and an adjustment mechanism 5 on the trapezoidal steel template 2. The adjustment mechanism 5 includes a fixing plate 501, which is fixed to the vertical side plate 202. A sliding plate is located on the right side of the fixing plate 501. There are telescopic bolts between the movable plate 503, the fixed plate 501 and the sliding plate 503. The telescopic bolts include a double-acting screw 502 and a screw sleeve 504. The screw sleeves 504 are fixed on the fixed plate 501 and the sliding plate 503 respectively. The double-acting screw 502 is threaded between the two screw sleeves 504. The wooden template 3 is convex in shape. There are contact plates 301 on both sides of the wooden template 3. The contact plates 301 contact the sliding plate 503.
